A Quaint Collation of Childhood Renal Neoplasms- Wilms and Beyond: Perspective of a Tertiary Care Hospital of Eastern India

Abstract

Paediatric renal neoplasms are rarely encountered entities. Histopathology is essential in most of the cases, where there is significant degree of clinical and radiological overlap. Present series has 32 cases which aimed to evaluate clinical and pathologic spectrum of renal tumours in children. Nephrectomy specimens of renal neoplasms of children below 12 years of age were included. Haematoxylin and Eosin (H&E) staining and Immunohistochemistry (IHC) were done. Findings were tabulated in a master sheet along with other demographic variables, clinical histories and imaging findings. Abdominal lump was the commonest presentation. Wilms tumour was the major histologic variant (66%), followed by Congenital Mesoblastic Nephroma (13%). Anaplasia and advanced Children’s Oncology Group (COG) staging were the adverse prognostic indicators. Clear Cell Sarcoma and Rhabdoid tumours were seen to have adverse outcomes, whereas Congenital Mesoblastic Nephroma, Multicystic Dysplastic Kidney and Paediatric Cystic Nephromas had overall favorable prognosis. Histopathology plays a key role for confirmatory opinion on nature of the neoplasm. Better understanding of these cases will increase the diagnostic accuracy with early implementation of definitive therapy.
